Hmm.. Sixty, I am not so sure that you will get what you see in the picture. That seller posts the wrong pictures sometimes. See how the description text says that it is a "IBM" model "M" with an "AZERTY" azerty while the layout in the pictures is Swedish. See how the pictures of the back of the keyboard at the top and within the description don't even show the same type of keyboard,
The seller has done this before. A few weeks before, I had noticed that he/she/them had half a dozen IBM Model Ms for sale .. and they all used the same picture of a Model M in Swedish layout. I asked if they really all were Swedish. I got the answer that most of them actually had a AZERTY layout and that the pictures should be changed, which they were later that day. After the change, none of the pictures showed a Swedish layout so I lost interest.
BTW, if you do get a Swedish/Finnish key-set of thick-walled PBT, I am interested in buying it from you.
